Final decision - Revocation and Substitution
Back to topOn 25 May the AER wrote to Ausnet indicating that it had revoked and substituted the 2016-20 regulatory determinations to correct for the inflation estimation error. As set out in the attached letter, the new determinations will have the effect of reducing the businesses revenue in the 2019 and 2020 regulatory years by the amount of the correction (in NPV terms).
Background
